And although Monaco has been handsomely recompensed, pulling in €155 million on those four transfers alone, their loss will be difficult to absorb.

Difficult, but not impossible. Manager Leonardo Jardim has had to deal with similar exits in the past. Indeed, under his guidance, AS Monaco have come back stronger.

But if the likes of Kylian Mbappe, Fabhino and Thomas Lemar join the exodus, then surely hopes of a serious title defence and another strong run in the Champions League will have to be written off.

On the flipside, with all still currently on the Monaco books, and with the arrival some interesting talent in the form of Youri Tielemans and Terrence Kongolo, Jardim’s men remain among the favourites for the French title.

Belgian central midfielder Tielemans (20) and Dutch central defender Kongolo (23) certainly fit the recruitment profile that has served Monaco so well in recent seasons.

Young, hungry and talented, the two arrived for €25 million and €15 million from title winning Anderlecht and Feyenoord, respectively.

Both are expected in time to become significant players for the club and to increase their value substantially, in line with the club’s model of buying the best young talent, developing it and selling at the top end of the market.

Of the two, only Tielemans featured – albeit in a brief cameo – in Friday night’s heard-earned win in Metz, as Jardim seeks to ease them into his squad.

The narrow 1-0 victory was Monaco’s third win in three this season and their 15th league win in a row – a new Ligue 1 record.

The win came courtesy of a 78th minute strike from Radamel Falcao who has begun the season in blistering form – scoring five in the three outings so far.

In all the talk of comings and goings at the club and about the wealth of young talent it has developed, it’s easy to forget just how Jardim has revitalised the Colombian.

The 31-year-old’s return of 30 goals in 43 appearances across all competitions last term could hardly have been envisioned given the feeble nature of his loan spells at Chelsea and Manchester United in recent seasons.

But despite Falcao’s best efforts on Friday evening, Monaco never really approached their best as they struggled to overcome a Metz side they pulverised twice last term.
